#     powerpc/64e: Fix amdgpu build on Book3E w/o AltiVec
#     
#     There's a build failure for Book3E without AltiVec:
#       Error: cc1: error: AltiVec not supported in this target
#       make[6]: *** [/linux/scripts/Makefile.build:250:
#       drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o] Error 1
#     
#     This happens because the amdgpu build is only gated by
#     PPC_LONG_DOUBLE_128, but that symbol can be enabled even though AltiVec
#     is disabled.
#     
#     The only user of PPC_LONG_DOUBLE_128 is amdgpu, so just add a dependency
#     on AltiVec to that symbol to fix the build.
